How much to decrease ratio by when shot is slightly bitter?

I’ve dialled in some beans from my local roaster that taste great but they’re just slightly bitter

I don’t want to go overboard when decreasing the ratio though and want to know what a good amount is to decrease the ratio by incrementally until I reach the flavour I want

  1. try it. Use big steps so you’ll easily know when you’ve gone too far.

  2. maybe ratio is not the control point you want to change. Maybe aim for a shorter contact time?

I think this is right. For bitterness I would start with decreasing time or temperature as it sounds like you are over-extracting currently.

I use brew ratio for finetuning: when I think my coffee is just a tiny bit too bitter, I would decrease output by maybe 1 - 2 grams. When I think, the effect is too little, I would grind a little coarser instead.

A bitter shot indicates overextraction as the bitter flavors come from the tail end of the process.

  1. Drop your ratio slightly. If your starting point is 18g in/36g out, try to stop at 35g or 34
  2. Your shot time should be 25-30s as a baseline. If you’re running faster than that (less than 25s) grind finer. And vice versa if you’re slower than 30s. This is just a baseline though. I typically run a 35-40s shot (20g in/45 out)

Pick one variable, and shift it slightly.

For bitter, I usually pick grind weight. So, if you’re putting 18g in, try 18.5g, but keep output the same. If adjusting the input, I usually adjust by 0.5g increments, then fine-tune as needed.

If you’d rather adjust the output, then adjust only that. So, using our example above, keep input at 18g, but decrease the output a measurable tad. If adjusting output, I usually adjust by 1g increments, then fine-tune as needed.

Generally, I’d rather adjust input, because output is sometimes harder to fine-tune.
